Abstract

Composition comprising in an physiologically acceptable medium, an oily phase dispersed in an aqueous phase, fibers, spherical particles and inserts.

Description

Composition containing fibers and their uses particularly in cosmetics.

This application refers to a composition comprising in a physiologically acceptable medium, an oily phase dispersed in an aqueous phase, fibers, particles spherical and inserts, and the use of the indicated composition, in particular for care, treatment and / or makeup of the skin of the body or face, of the hair, of the eyelashes and / or lips.

They are known by the document JP07-196440, cosmetic compositions containing short polyamide fibers, providing these to those indicated compositions a velvety touch and good behavior cosmetic. However, the incorporation of fibers, and in particular of these polyamide fibers, in the dispersions that they comprise an oily phase dispersed in an aqueous phase, and in particular in oil-in-water (H / E) emulsions that are dispersions stabilized by emulsifiers, poses problems in the application of the composition on keratin matters such as the skin, and this particularly when the amount of Fibers is important. Indeed, the fibers, particularly when they are in quite a significant amount, they tend to be added in the H / E emulsions that contain them. On the other hand, these fiber-containing emulsions have a tendency to "form pellets "on the skin, that is to say when applied en masse forming Like little balls on the skin.

The document EP-A-0106 762 describes the association of polyethylene fibers with silica, preferably amorphous and synthetic, in a cosmetic makeup product.

The need therefore remains H / E dispersions and particularly H / E emulsions that they contain fibers, and particularly polyamide fibers, even in significant amount, and they don't have the disadvantages of the prior art

The requesting firm has discovered unexpected than the fact of associating with the fibers, particles spherical and inserts allowed to avoid the problems of formation of pellets and aggregation, due to the fibers, and perform oil-in-water emulsions containing fibers, which do not pose problems in the application on the skin, even in the presence of a significant amount of fibers

The present invention relates to a composition comprising in a physiologically acceptable medium, an oily phase dispersed in an aqueous phase, fibers, particles spherical and inserts.

It is understood here by "physiologically medium acceptable "means compatible with keratin materials and particularly the skin, lips, scalp, eyelashes, eyes and / or hair.

The dispersion may be more particularly a H / E emulsion.

The association used allows not only prevent the fibers from agglomerating, but also facilitate the application of the composition that contains them, on the materials keratin and in particular on the skin. So, the composition according to the invention it does not "form pellets" and therefore not form small balls in the application on the skin. Also I know easily diluted, that is to say that it is applied and deposited in a sufficient and homogeneous amount on the skin or matter Keratin where it is applied. This effect of the association of inserts and spherical particles are checked for all composition containing fibers and particularly for dispersions of the invention.

The object of the invention is also the cosmetic use of the association of inserts and particles spherical in a cosmetic composition containing fibers, for prevent the fibers from agglomerating, to prevent the formation of balls of the composition and to facilitate the application (and the unleashed) of the composition on keratinous materials and particularly on the skin.

It is understood in the present application by "spherical particles" particles that have the form or substantially the shape of a sphere, insoluble in the middle of the composition according to the invention, even at the temperature of medium melting (approximately 100 ° C.)

It is also understood here by "inserts" or "lamellae" particles of parallelepipedic form (surface rectangular or square), discoidal (circular surface) or ellipsoidal (oval surface), characterized by three dimensions: a length, a width and a height, particles that are insoluble in the medium of the composition according to the invention, even at medium melting temperature (approximately 100 ° C).

The composition of the invention may comprise one or more kinds of fibers, one or more kinds of particles spherical and one or several kinds of inserts.
